What is perfusion?
Perfusion denotes blood flow through the blood vessels of the body on the way to capillary beds in various tissues that receive blood. When someone experiences reduced perfusion, it can be quite dangerous because the tissue in the body can be quickly damaged by limited blood flow. Most people who have repeated the rubber band around the finger for a short time are familiar with what happens when perfusion decreases. Limited perfusion can be a sign of a serious problem that needs to be solved. One of the common ways to test perfusion is simply to put pressure on the skin and then wait until we see how long it takes for blood to flow back to the place. The slow blood return indicates reduced perfusion, the cause of fear, capillaries. As blood flows through the capillaries, it brings vital nutrients into the body tissues and helps sweep waste. Then the blood flows back to the heart, where it is filled with oxygen and sets off again. Any interruption of this circulatory system may have the ripple to the blood vessels and capillaries downstream.
The perfusion process can be turned into the advantage of medical staff. For example, many medicines are supplied directly to the bloodstream, with perfusion carrying medicines throughout the body. Sometimes the blood flow to a specific limb or area can be briefly limited, while drugs are injected on site, ensuring that medicines are focused in the area where it is most needed.
When the perfusion is radically decreased, the patient risks that he dies or loses his limb. For example, if Someone is in a car accident that causes it to be trapped in a car with a leg clipped, the circulation may be cut off to this leg, causing the tissues to die in the leg. If the patient is not treated immediately, it may be necessary to amputate the limb due to widespread tissue death. Poor perfusion can also cause organ failure, which may be a very serious problem, because the failure of one organ often emphasizes others, leading to systemic failure of organs and possible death.
